New research out of Duke University could put an end to painful sunburns. Scientists have discovered a way to block TRP-V-4, a skin molecule responsible for the redness and pain following prolonged sun exposure.

"Like reddening, formation of soreness and blisters... influx of blood, inflammatory cells, of cells that make itch," said Wolfgang Liedtke, a neurobiology professor at Duke. "That is the tissue injury response down to the level of non-visible."
